Abstract
A method and apparatus for applying assistance information for traffic steering between a 3rd generation partnership project (3GPP) access network and a non-3GPP access network in a wireless communication system is provided. A user equipment (UE) receives assistance information for traffic steering through a dedicated signaling from an eNodeB (eNB), and starts a timer upon entering an idle mode. The UE applies the assistance information received through the dedicated signaling until the timer expires. After the timer expires, the UE applies assistance information received through a broadcast signaling.
Claims20
A method for applying assistance information for traffic steering between a 3rd generation partnership project (3GPP) access network and a non-3GPP access network by a user equipment (UE) in a wireless communication system, the method comprising:
- while in a radio resource control (RRC) connected mode:
- receiving first assistance information for traffic steering via a dedicated signaling from an eNodeB (eNB);
- applying the first assistance information for traffic steering;
- transiting from the RRC connected mode to a RRC idle mode;
- while in the RRC idle mode:
- keeping applying the first assistance information for traffic steering;
- performing a cell reselection while the first assistance information is valid;
- and
- clearing the first assistance information.
A user equipment (UE) in a wireless communication system, the UE comprising:
- a memory;
- a radio frequency (RF) unit;
- and
- a processor, operably coupled to the memory and the RF unit, that;
- while in a radio resource control (RRC) connected mode:
- controls the RF unit to receive first assistance information for traffic steering via a dedicated signaling from an eNodeB (eNB);
- applies the first assistance information for traffic steering;
- transits from the RRC connected mode to a RRC idle mode;
- while in the RRC idle mode:
- keeps applying the first assistance information for traffic steering;
- performs a cell reselection while the first assistance information is valid;
- and
- clears the first assistance information.
